Eulerian Marketing Platform MCP Server

A Model Context Protocol (MCP) proxy server that bridges AI assistants (Claude Desktop, Gemini CLI, etc ...) to a remote Eulerian Marketing Platform MCP server. This proxy handles authentication, request forwarding, and provides a local MCP interface to your remote Eulerian instance.

How It Works

This server acts as a transparent proxy between local MCP clients and your remote Eulerian Marketing Platform server:

code

┌─────────────┐        ┌──────────────────┐        ┌────────────────┐
│   Claude    │ ◄─────►│  This MCP Proxy  │◄─────► │ Remote Eulerian│
│   Desktop   │  stdio │  (Local)         │  HTTP  │  MCP Server    │
└─────────────┘        └──────────────────┘        └────────────────┘

The proxy:

🔐 Handles authentication with your remote Eulerian server
📡 Forwards MCP requests via HTTP with Bearer token
🛠️ Exposes remote tools and resources to AI assistants
📝 Provides comprehensive logging for debugging
⚡ Uses async HTTP for better performance

Warning

Given the rapid pace of evolution of protocols, implementations and new features coming out, the MCP may or may not be compatible with your suite of tools. Please fill in an issue so that we can check it.

Setup Instructions by Client

1. Claude Desktop

Two installation methods are available. The DXT extension is the easiest — no terminal required.

Option A: One-click DXT Extension (Recommended)

Desktop Extensions (DXT) let you install MCP servers in Claude Desktop with a single double-click, without editing JSON config files.

Requirements: Python 3.10+ with the package installed:

bash

pip install eulerian-marketing-platform

Install steps:

Download the latest .dxt file from the releases page
Double-click the .dxt file — Claude Desktop opens an installation dialog
Enter your API Endpoint and API Token when prompted
Click Install — the server is ready immediately

That's it. No pip install, no config file editing, no restart required.

To update: download the new .dxt and double-click it again.

Option B: Manual JSON configuration

Claude Desktop supports local MCP servers via stdio transport.

Configuration File Locations

Windows: %APPDATA%\Claude\claude_desktop_config.json
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Linux: ~/.config/Claude/claude_desktop_config.json

Setup Steps

Open Claude Desktop
Access configuration:
- Click Claude menu → Settings → Developer → Edit Config
- Or manually edit the JSON file at the location above
Add the server configuration:

json

{
  "mcpServers": {
    "eulerian-marketing-platform": {
      "command": "python",
      "args": ["-m", "eulerian_marketing_platform.server"],
      "env": {
        "EMP_API_ENDPOINT": "https://your-eulerian-instance.com/mcp",
        "EMP_API_TOKEN": "your_authentication_token_here"
      }
    }
  }
}

Restart Claude Desktop
Verify the connection:
- Look for a hammer/tools icon (🔨) in the bottom-right corner
- Click it to see available Eulerian tools
- Ask Claude: "What Eulerian Marketing Platform tools do you have access to?"

Platform-Specific Notes

Windows:

Use the Run dialog (Win + R) and enter %APPDATA%\Claude to quickly navigate to the config directory
If using a local installation, ensure Python is in your PATH

Linux:

The config directory may not exist initially - create it with: mkdir -p ~/.config/Claude

macOS:

Access the config via Finder: Cmd + Shift + G → ~/Library/Application Support/Claude/

2. Gemini CLI

Gemini CLI supports MCP servers through its configuration file.

Prerequisites

Install Gemini CLI if you haven't already:

bash

npm install -g @google/gemini-cli

Configuration File Location

~/.gemini/settings.json

Setup Steps

Create or edit the settings file:

bash

# Create the directory if it doesn't exist
mkdir -p ~/.gemini

# Edit the settings file
nano ~/.gemini/settings.json

Add the MCP server configuration:

json

{
  "mcpServers": {
    "eulerian-marketing-platform": {
      "command": "python",
      "args": ["-m", "eulerian_marketing_platform.server"],
      "env": {
        "EMP_API_ENDPOINT": "https://your-eulerian-instance.com/mcp",
        "EMP_API_TOKEN": "your_authentication_token_here"
      }
    }
  }
}

Start Gemini CLI:

bash

gemini

Verify the connection:
- Use the /mcp command to see connected servers
- Ask Gemini: "What tools are available from the Eulerian Marketing Platform?"

Platform-Specific Notes

Windows:

Settings file location: %USERPROFILE%\.gemini\settings.json
Create directory: mkdir %USERPROFILE%\.gemini

Linux/macOS:

Standard location: ~/.gemini/settings.json

3. Codex CLI

Codex CLI supports MCP servers configured in ~/.codex/config.toml. The configuration is shared between the CLI and the Codex IDE extension (VS Code).

Prerequisites

Node.js 18+ and npm
Codex CLI installed: npm install -g @openai/codex
Python 3.10+ with this package installed (pip install eulerian-marketing-platform)
A ChatGPT Plus, Pro, Team, Edu, or Enterprise subscription (or an OpenAI API key)

Option A: Using the `codex mcp add` command (easiest)

Run the following command to register the Eulerian MCP server:

bash

codex mcp add eulerian-marketing-platform \
  --env EMP_API_ENDPOINT=https://your-eulerian-instance.com/mcp \
  --env EMP_API_TOKEN=your_authentication_token_here \
  -- python -m eulerian_marketing_platform.server

That's it — Codex will update ~/.codex/config.toml for you.

Option B: Edit `config.toml` manually

Open (or create) ~/.codex/config.toml and add the following:

toml

[mcp_servers.eulerian-marketing-platform]
command = "python"
args = ["-m", "eulerian_marketing_platform.server"]
tool_timeout_sec = 300

[mcp_servers.eulerian-marketing-platform.env]
EMP_API_ENDPOINT = "https://your-eulerian-instance.com/mcp"
EMP_API_TOKEN = "your_authentication_token_here"

Note: The section name must use mcp_servers (with an underscore). Using mcp-servers or any other variant will silently fail.

Option C: Project-scoped configuration

To limit the MCP server to a specific project, create a .codex/config.toml file at the root of that project with the same content as above. The project must be marked as trusted by Codex.

Verify the connection

Launch Codex in your terminal:
bash
```
codex
```
Type /mcp in the interactive TUI to see all connected MCP servers.
Confirm that eulerian-marketing-platform appears in the list with its available tools.

Try asking:

code

What Eulerian Marketing Platform tools do you have access to?

Managing the server

bash

# List all configured MCP servers
codex mcp

# Remove the server
codex mcp remove eulerian-marketing-platform

Troubleshooting (Codex CLI)

Server not appearing in /mcp: Verify that the [mcp_servers.eulerian-marketing-platform] section is present in ~/.codex/config.toml and that the TOML syntax is valid.
Timeout errors: Increase tool_timeout_sec in config.toml (default is 60 seconds). Eulerian queries can take longer, so 300 is recommended.
Authentication errors: Double-check that EMP_API_ENDPOINT and EMP_API_TOKEN are correct.
Python not found: Ensure the python command resolves to Python 3.10+. You may need to use python3 instead:
toml
```
command = "python3"
```
Package not found: Make sure eulerian-marketing-platform is installed in the Python environment that Codex will invoke. Run python -m eulerian_marketing_platform.server manually to confirm it works.
Check logs: Monitor the proxy logs for detailed error information:
bash
```
tail -f /tmp/eulerian-mcp-proxy.log
```

4. Claude Code

Claude Code is Anthropic's terminal-based coding agent. It supports MCP servers configured via the claude mcp CLI command or by editing ~/.claude.json.

Prerequisites

Node.js 18+ and npm
Claude Code installed: npm install -g @anthropic-ai/claude-code
Python 3.10+ with this package installed (pip install eulerian-marketing-platform)
An Anthropic API key or Claude subscription

Option A: Using the `claude mcp add` command (easiest)

bash

claude mcp add eulerian-marketing-platform \
  -e EMP_API_ENDPOINT=https://your-eulerian-instance.com/mcp \
  -e EMP_API_TOKEN=your_authentication_token_here \
  -- python -m eulerian_marketing_platform.server

By default this adds the server with local scope (current project only). To make it available in all projects, add the -s user flag:

bash

claude mcp add -s user eulerian-marketing-platform \
  -e EMP_API_ENDPOINT=https://your-eulerian-instance.com/mcp \
  -e EMP_API_TOKEN=your_authentication_token_here \
  -- python -m eulerian_marketing_platform.server

Option B: Edit `~/.claude.json` manually

Open ~/.claude.json and add the server under the mcpServers key:

json

{
  "mcpServers": {
    "eulerian-marketing-platform": {
      "type": "stdio",
      "command": "python",
      "args": ["-m", "eulerian_marketing_platform.server"],
      "env": {
        "EMP_API_ENDPOINT": "https://your-eulerian-instance.com/mcp",
        "EMP_API_TOKEN": "your_authentication_token_here"
      }
    }
  }
}

Verify the connection

Launch Claude Code:
bash
```
claude
```
Type /mcp to see the status of all connected MCP servers.
Confirm that eulerian-marketing-platform appears and shows as connected.

Try asking:

code

What Eulerian Marketing Platform tools do you have access to?

Managing the server

bash

# List all configured MCP servers
claude mcp list

# Get details for a specific server
claude mcp get eulerian-marketing-platform

# Remove the server
claude mcp remove eulerian-marketing-platform

Troubleshooting (Claude Code)

Server not appearing in /mcp: Run claude mcp list to confirm it is registered. Check ~/.claude.json for JSON syntax errors.
Python not found: Ensure the python command resolves to Python 3.10+. You may need to use python3 instead.
Package not found: Make sure eulerian-marketing-platform is installed in the Python environment that Claude Code will invoke.
Debug mode: Launch Claude Code with verbose MCP logging:
bash
```
claude --mcp-debug
```
Check logs: Monitor the proxy logs for detailed error information:
bash
```
tail -f /tmp/eulerian-mcp-proxy.log
```

5. Cursor

Cursor is an AI-powered code editor with built-in MCP support.

Prerequisites

Cursor installed (download from cursor.com)
Python 3.10+ with this package installed (pip install eulerian-marketing-platform)

Configuration File Location

Global: ~/.cursor/mcp.json
Project-scoped: .cursor/mcp.json in your project root

Setup Steps

Open (or create) the configuration file:

bash

# Global configuration
mkdir -p ~/.cursor
nano ~/.cursor/mcp.json

Add the MCP server configuration:

json

{
  "mcpServers": {
    "eulerian-marketing-platform": {
      "command": "python",
      "args": ["-m", "eulerian_marketing_platform.server"],
      "env": {
        "EMP_API_ENDPOINT": "https://your-eulerian-instance.com/mcp",
        "EMP_API_TOKEN": "your_authentication_token_here"
      }
    }
  }
}

Restart Cursor to load the new configuration.
Verify the connection:
- Open Cursor Settings → Tools & Integrations → MCP Servers
- Confirm that eulerian-marketing-platform appears and shows a green status
- Switch to Agent mode in the Copilot pane
- Ask: "What Eulerian Marketing Platform tools do you have access to?"

Platform-Specific Notes

Windows:

Global config file: %USERPROFILE%\.cursor\mcp.json
If python is not in your PATH, use the full path to the Python executable in the command field.

macOS/Linux:

Standard location: ~/.cursor/mcp.json

Troubleshooting (Cursor)

Server not appearing: Verify that ~/.cursor/mcp.json contains valid JSON. Restart Cursor after any config change.
Tools not available: Make sure you are in Agent mode (not Ask mode) in the Cursor chat panel.
Python not found: Ensure the python command resolves to Python 3.10+. You may need to use python3 or a full path.
Check logs: Monitor the proxy logs:
bash
```
tail -f /tmp/eulerian-mcp-proxy.log
```

6. VS Code / GitHub Copilot

Visual Studio Code supports MCP servers through GitHub Copilot's Agent mode. MCP requires VS Code 1.101 or later.

Prerequisites

VS Code 1.101+ with the GitHub Copilot extension
Python 3.10+ with this package installed (pip install eulerian-marketing-platform)
A GitHub Copilot subscription

Configuration File Locations

Workspace: .vscode/mcp.json in your project root (recommended)
User/Global: accessible via the command MCP: Open User Configuration

Note: VS Code uses a "servers" key (not "mcpServers") inside mcp.json.

Setup Steps

Create the workspace configuration file:

bash

mkdir -p .vscode
nano .vscode/mcp.json

Add the MCP server configuration:

json

{
  "servers": {
    "eulerian-marketing-platform": {
      "type": "stdio",
      "command": "python",
      "args": ["-m", "eulerian_marketing_platform.server"],
      "env": {
        "EMP_API_ENDPOINT": "https://your-eulerian-instance.com/mcp",
        "EMP_API_TOKEN": "your_authentication_token_here"
      }
    }
  }
}

Alternatively, to make the server available globally across all workspaces, add the configuration to your User Settings (JSON) (Ctrl+Shift+P → Preferences: Open User Settings (JSON)):

json

{
  "mcp": {
    "servers": {
      "eulerian-marketing-platform": {
        "type": "stdio",
        "command": "python",
        "args": ["-m", "eulerian_marketing_platform.server"],
        "env": {
          "EMP_API_ENDPOINT": "https://your-eulerian-instance.com/mcp",
          "EMP_API_TOKEN": "your_authentication_token_here"
        }
      }
    }
  }
}

Start the MCP server:
- Open the .vscode/mcp.json file in the editor
- Click the Start button that appears above the server definition (code lens)
- Or use the Command Palette: MCP: List Servers → select the server → Start
Verify the connection:
- Switch to Agent mode in the GitHub Copilot Chat panel (toggle located near the chat input)
- Click the Tools button (🔧) in the Copilot pane to see available Eulerian tools
- Ask: "What Eulerian Marketing Platform tools do you have access to?"

Using input variables for secrets

To avoid hardcoding your token, you can use VS Code input variables:

json

{
  "inputs": [
    {
      "type": "promptString",
      "id": "empToken",
      "description": "Eulerian Marketing Platform API Token",
      "password": true
    }
  ],
  "servers": {
    "eulerian-marketing-platform": {
      "type": "stdio",
      "command": "python",
      "args": ["-m", "eulerian_marketing_platform.server"],
      "env": {
        "EMP_API_ENDPOINT": "https://your-eulerian-instance.com/mcp",
        "EMP_API_TOKEN": "${input:empToken}"
      }
    }
  }
}

VS Code will prompt you for the token when the server starts.

Troubleshooting (VS Code)

MCP not available: Ensure you are running VS Code 1.101 or later and have the GitHub Copilot extension installed and enabled.
Tools not appearing: MCP tools only work in Agent mode. Toggle to Agent mode in the Copilot Chat panel.
Start button not showing: The code lens (Start button) only appears if the .vscode folder is at the root of your workspace.
Python not found: Ensure the python command resolves to Python 3.10+. You may need to use python3 or a full path.
Check logs: Monitor the proxy logs:
bash
```
tail -f /tmp/eulerian-mcp-proxy.log
```

Usage Examples

Once configured with any client, you can interact with your remote Eulerian Marketing Platform:

code

User: "What tools are available from Eulerian?"
→ Proxy calls list_remote_tools() and returns all available tools

User: "Call the update_goal tool"
→ Proxy forwards to remote server and update goal settings

User: "Show me campaign details for CAMP-12345"
→ Claude uses call_eulerian_tool() to fetch specific campaign

User: "What resources are available?"
→ Proxy lists all available data sources

The AI assistant will automatically use the appropriate proxy tools to fulfill your requests.

Viewing Logs

Monitor proxy activity in real-time:

bash

# Default log location
tail -f /tmp/eulerian-mcp-proxy.log

# Custom log location
tail -f /var/log/eulerian-mcp-proxy.log

You'll see detailed logging of:

Requests to the remote server
HTTP responses and status codes
